With global population numbers predicted to reach 8.5 billion by 2030, there is no doubt that an increasing population will place extra pressure on the planet and its resources to provide food, housing, healthcare and employment.
Add to this the challenge of handling environmental issues, such as global warming, rising sea levels and a growing number of extreme weather occurrences, and it becomes clear that this is a megatrend that requires intense scrutinization and rapid action.
Resource scarcity extends beyond what is needed to eat or build homes. It also includes fuel for vehicles and machinery, base components for manufacturing and materials used for day-to-day goods.
This megatrend is not only about climate change and resource scarcity, but also about how these issues must be answered.
What is climate change and resource scarcity?
Climate change and resource scarcity. An expanding population and the rising demand for food, energy and materials continue to strain the finite resources of the planet. The need for solutions that improve energy efficiency, lower food waste and provide alternatives to scarce resources has never been greater.
How does climate change affect resources?
Climate change has both direct and indirect effects on agricultural productivity including changing rainfall patterns, drought, flooding, and the geographical redistribution of pests and diseases. Conflict can arise when natural resources are not equitably managed.
Impacts of climate change on our natural resources warming streams and lakes that reduce cold water fish habitats, resulting in a decline in certain fish species and recreational fishing opportunities.
How will climate change affect us?
Climate change is already impacting human health. Changes in weather and climate patterns can put lives at risk. Heat is one of the most deadly weather phenomena. As ocean temperatures rise, hurricanes are getting stronger and wetter, which can cause direct and indirect deaths.
Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. … These human-produced temperature increases are commonly referred to as global warming.
What are the effects of climate change and global warming?
- rising maximum temperatures.
- rising minimum temperatures.
- rising sea levels.
- higher ocean temperatures.
- an increase in heavy precipitation (heavy rain and hail)
- shrinking glaciers.
- thawing permafrost.
The Top 10 Causes of Global Warming
- Power Plants. Forty percent of U.S
- Carbon dioxide emissions stem from electricity production
- Oil Drilling
- Natural Gas Drilling
Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.
The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.
- Burning fossil fuels
- Deforestation & Tree-Clearing
- Agriculture & Farming
Human activities—mostly burning of coal and other fossil fuels, but also cement production, deforestation and other landscape changes—emitted roughly 40 billion metric tons of carbon dioxide in 2015.
What causes global warming for kids?
The primary cause is greenhouse gas emissions from cars, power plants and other human-made sources—rather than natural variations in climate. … Greenhouse gases act like a blanket, trapping the sun’s warmth near the earth’s surface, and affecting the planet’s climate system.
Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
